I saved the same image as RGBA4444 and RGBA8888, but they have the same texture memory.
In theory, RGBA4444 should have only half the memory.
I saw the 2012 article Solar all uses RGBA8888.
But in 2016 @vlads mention,
“Corona uses various texture formats depending on a platform. Not all textures are represented as RGBA8888.”
I want to know if there are other formats, or are they still in RGBA8888 format?
